MALIALIM® HKM-150A
MALIALIM™ series are new functional polymers that have polyoxyalkylene groups on side chain. The property of MALIALIM™ series varies according to the structure of polyoxyalkylene group such as molecular weight, type of alkyleneoxide, etc. MALIALIM™ series can be used by many kinds of applications, such as dispersant for inorganic or organic powders, synthetic resin compatibilizer, etc. MALIALIM™ series are no-ash type (does not contain metal atoms), so that are suitable as a dispersant for ceramics manufacturing.
MALIALIM™ series are comb polymers that have polyoxyalkylene groups on side chains and ionicity groups on main chain.
Ionicity groups (on main chain) act as segments that adsorb the surface of powder etc., and polyoxyalkylene groups (on side chains) give steric-repulsion effects or act as segments by which dissolution is improved. MALIALIM™ series which is comb polymer can demonstrate more excellent performance than the linear polymers.
